To always have this crumb at home, store leftover pigeon meat without bones in the freezer and partially freeze it (meaning until the pigeon becomes tender). Then put it in a food-grade plastic bag. When you're ready to use it, remove the frozen pigeon from the freezer and grate it still frozen. Leave what's left in the freezer. It lasts for up to 3 months.
